Earth, Barnard's star and small rocky planets

Four small rocky planets confirmed orbiting nearby Barnard's star
Astronomers have identified a quartet of small rocky planets orbiting Barnard's star - one of our closest stellar neighbors - though they concluded that all of them are too hot to harbor life, much like our solar system's innermost planet Mercury.
Four tiny planets found orbiting one of Earth's nearest stars in 'incredible' discovery
Barnard's Star is the second-nearest star system to Earth, and four tiny planets have been discovered around it
This 'super-Earth' orbits its star in 647 days like Mars
With an orbit of 647 days, HD 20794 d is similar to Mars in our solar system. However, its orbit around the star is highly elliptical. This feature causes extreme temperature variations on the planet, swinging from intense heat to deep freeze every 300 days.
4 rocky exoplanets found around Barnard's Star, one of the sun's nearest neighbors
After many previous claims and false alarms, astronomers can finally confirm the existence of at least four planets less massive than Earth orbiting Barnard's Star.

Four small planets discovered around one of the closest stars to Earth – an expert explains what we know
Consequently, even though it is one of the closest stars to Earth, such that its light takes only six years to get here, it is too faint to be seen with the naked eye. Now, four small planets have been found orbiting the star.
